Sketch Booth can be run in offline mode if there is no Internet. If there is a red dot on the Queue tab, that is the notification that there are items in the queue. Emails, SMS and Client Facebook uploads can be queued and uploaded once you are back online. User Facebook and Twitter can't be queued as the user needs to actually login to those services to upload.

Note: If you don't want to send the queued files or are getting an error while trying to send them, you can delete the queue by looking for the following files in your Event folder:
